Abstract
The present invention proposes a kind of compound formaldehyde scavenger, is made up of the component of following percetage by weight：Imidazolidinone, imidazolone or its mixture 3~5%, urea 2~3% and metal chloride 1~2%, surplus is water.The scavenger can be quick, efficient, lasting purification air, nonpoisonous and tasteless, safety and environmental protection.
Description
Technical field
The invention belongs to eliminate formaldehyde technical field, and in particular to a kind of compound formaldehyde scavenger.
Background technology
Formaldehyde chemical formula is HCHO, is colourless gas at normal temperatures, there is special penetrating odor, due to its special change
Performance is learned, is largely used in chemical industry and fur industry.
Industrially, such as urea-formaldehyde resin adhesive, melamine resin adehsive and phenolic resin glue adhesive all using formaldehyde as
Primary raw material, and these adhesives are widely used in the production of the sheet materials such as glued board, Blockboard and density board.So
Outside, this kind of adhesive will be used in the metope of building, ground, the finishing of furniture and auxiliary equipment.
In fur industry, formaldehyde tanning agent is a kind of widely used post-treatment agent, and the leather colour purity of leather can be made white, meets light
It is non-discolouring, and absorption of perspiration is strong, and the free formaldehyde remained in these products can slowly discharge, and release process is even up to more than ten
Year.
Having many uses for formaldehyde is general, but harm is very big, and the harm especially to human body, formaldehyde in air content exceedes
During 0.1mg/m3, people are with regard to that can smell a strange smell and not feel well, when content of formaldehyde is more than 0.5mg/m3When, eyes can be felt to stimulate
Sense, while trigger and shed tears, when concentration is higher, headache, nausea, cough, vomiting, uncomfortable in chest and shortness of breath etc. can be triggered, seriously can be anti-
Answer too drastic and cause death.Long Term Contact formaldehyde, human body constitution are easily deteriorated, immunity degradation, cause headache and insomnia etc., seriously
Lesion tissue and cancer can be caused.
In addition, the material containing formaldehyde, such as furniture of finishing etc., it is various different also to bring hydrogen sulfide and amine substance etc. into
Taste, it is the material for making one not feeling well, great health effect can be brought.
Current air clearing product respectively has feature, and there is also certain deficiency.As adsorptivity product is easily saturated, and it is right
The absorption of pollutant is not firm, easy secondary volatilization；Ozone purification speed is fast but continuation is poor；Common formaldehyde scavenger is removed
Efficiency is low, continuation is poor；Air purifier space-consuming and consumption resource.
The content of the invention
A kind of compound formaldehyde scavenger of present invention proposition, the purification air that the scavenger can be quick, efficient, lasting,
It is nonpoisonous and tasteless, safety and environmental protection.
The technical proposal of the invention is realized in this way：
A kind of compound formaldehyde scavenger, is made up of the component of following percetage by weight：
Imidazolidinone, imidazolone or its mixture 3~5%, urea 2~3% and metal chloride 1~2%, surplus
For water.
Preferably, the imidazolidinone is 2- imidazolidinones, 1-Chlorocarbonyl-2-Imidazolidone or N- ethoxys -2-
Imidazolidinone.
Preferably, the imidazolone is DMI.
Preferably, the metal chloride is sodium chloride or calcium chloride
The preparation method of the compound formaldehyde scavenger of the present invention is that said components are mixed evenly i.e. according to proportioning
Can.
The compound formaldehyde scavenger application method also very simple of the present invention, is sprayed according to 10~30 milliliters/square metre
Or brush in sheet material, furniture, wallpaper, carpet.
The present invention is removed by the use of imidazolidinone, imidazolone or its mixture, urea as the formaldehyde removing of active ingredient
Taste agent, chemical reaction can be produced with free formaldehyde, and 2- imidazolidinones and urea can react with formaldehyde, and production stability is high
Polymer, prevent back reaction, cause the spilling of formaldehyde, so as to reach remove formaldehyde effect.
The urea of small molecule has diffusivity and permeability, can be deep into inside sheet material, and formaldehyde reacts, generation
The passage of thing energy closed methanal release.
Metal chloride has hygroscopicity, holding surface can be in moisture state for a long time, promote the reaction with formaldehyde.
Beneficial effects of the present invention：
1st, the purification air that compound formaldehyde scavenger of the invention can be quick, efficient, lasting, nonpoisonous and tasteless, safety
Environmental protection.
2nd, compound formaldehyde scavenger Chinese Academy of Sciences Guangzhou chemical analysis test Spot detection of the invention, Formaldehyde decomposition rate are
97.6%, while also have good degradation rate to other pollutant benzene, ammonia, TVOC.Through in Chinese Academy of Sciences's Guangzhou chemical analysis test
The heart detects, and security is good, non-stimulated to skin.
